SPECIFICATION forming part of Letters Patent No. 767,444, dated August16, 1904.

Application filed October 1,1902. Serial No. 125,458. (No model.)

Tr) all lull/rmt t Nte/,y concern:

Be it known that I, THURBUR F. RUSSELL, of Newton, county of Middlesex,and State of Massachusetts, have invented an Improvement inPaper-hhstening Devices, of which the following' description,'inconnection with the accompanying' drawings, is a specification, likeletters on the drawings representing' like parts.

The present invention relates to a paperfastening device, and isembodied in a machine for fastening together sheets of paper and thelike, the object of the invention being' to obtain an efficient anddurable machine for this purpose which is simple in construction andeasily operated. The machine embodying the invention is so arranged thattwo movements of an actuating device will result in punching the sheetsof paper to be fastened and subsequently inserting' in the punchedopening' a suitable fastening device, the machine being especiallyadapted to be used with eyelets of the kind commonly employed inshoe-uppers and frequently used for fastening' papers. The machine isentirely automatic in its operation, comprising' a support for thepapers to be fastened, a punch and setting device, an automatic feed forthe fasteners, and a single actuator adapted to cause the machine toperform the complete operation of punching the papers and feeding andsetting' the fastening device.

The invention is herein shown as embodied in a machine adapted toutilize eyelets for fastening devices, and comprises a punchingdie andits cooperating member and a setting device and its cooperating member,both of which are mounted on a reciprocating carriage which is adaptedto move back and forth relatively to a stationary support for thepapers.

The punch and setting device are provided with a common actuating memberadapted by its movement in one direction to cause the operation of thepunch and by its movement in the opposite direction to cause theoperation of the setting' device, the said actuating member being alsoconnected with the carrier for the punch and setting device, so as tomove the said carrier between the successive operations of the punch andsetting' device to remove the punch from its operating position and tobring the setting device to the same position, so as to be in alinementwith the hole or perforation made in the papers by the punch.Cooperating with the setting device is a feed member to supply fasteningdevices to the setting device, so that at the time when said setting'device is moved to its operative position it has already been suppliedwith a fastening device to be set in the previously-punched hole in thepapers. As herein shown, the lower member of the setting device isprovided with a pin or support Which is arranged to be held Hush withthe lower setting member during the movement of said member toward asuitable feed-chute, which is supplied with eyelets and which has at itslower end a yielding stop for the eyelets, the said pin being arrangedto move upward and engage an eyelet at the time when said lower memberis below the chute. eating' movement of the carrier for the punch andsetting device after the hole has been punched in the papers the eyeletis carried along upon the pin, so as to be presented to the punchedopening, and in the setting operation the pin is depressed and retainedin its depressed position until it again reaches the chute ready to pickup an eyelet.

The machine is further provided with a retaining device to hold thepapers in position during' the punching and setting operation, the saidretaining' device being so arranged as to move into contact with thepapers in response to the first movement of the actuating device whichproduces the punching operation and to remain in engagement with thepapers during' the subsequent operation of the machine, being nallyreleased after the papers have been fastened.

Figure l is a side elevation of a machine embodying' the invention; Fig.'2, a partial front elevation of the same, partly in section; Fig. 3, atransverse vertical section; Fig'. 4, a partial underneath plan view.Fig. 5 is a longitudinal section showing' the parts of the machineduring the punching' operation, and Fig. 6 is a similar View showing theparts of the machine at the end of the setting operation.

Referring to Fig. 5, the punch L and upper In the recipro- IOO setting'device /1 are mounted so as to be long'itudinally movable in areciprocating' carriag'e c, which is adapted to slide upon the bed orframe A of the machine, the said carriage having' wings rfi, Figs. 2 and3, which are held in position by means of plates A2, which are securedto the frame so as to overlie the said wings and to afford lateralg'uides for a portion of the carriage above the said wings.

'lhe punch /r is shown as a plung'er litting' a vertical opening' in thecarriage c and having' a shoulder H2, between which and the bottom ofthe opening' is interposed a spring' at, which tends to hold the punchin the position shownin Figs. l and 6. 'lhe said punch is provided witha cutting-die f/X, which is adapted to enter a corresponding' female diefr," in the body portion of the carriage c, so that when the said punchL is depressed with sheets of paper between it and the die a" it willpunch a hole Vfor the reception of a suitable lastening' device. Thesetting-die is also arranged to cooperate with a corresponding' memberf, which supports the rim of the eyelet while the shank is beingl`crushed into engagement with the papers to be fastened. ',lhe carriage cis arranged to be reciprocated through the action of a lever (Z, whichis pivotally supported at Z2 and provided with a slot d, which engages apin or projection c from the carriage c, so that when the said lever /Zis swung' upon its pivot (Z2 it will cause the carriage c to move backand forth along' the Vframe A, upon which it is supiiorted. The saidlever (Z is shown as arranged to be actuated by means of a cam-groove e,formed in a member e, which is shown as a plate snitably secured upon anoscillating shaft f, to which is also secured the actuating-handle g.The same actuating-handle is arranged to cooperate also with the punch aand the upper setting' device 7) and has a considerable range ofmovement, the camgroove a, therefore, being' shaped so as to produce nomovement of the cam-roll (Z1 and the lever (Z during' a greater partofits throw, the said movement taking' place at about the middle of thecomplete movement of the handle y, as shown in the drawings.

Starting, for example, from the position shown in Fig'. l and moving'the actuator f/ to the position shown in Fig'. 5, the cam-roll (Z willremain in the portion e of the cam-groove cut in the member a2, the saidportion being' curved on an arc struck Afrom the center of movement ofsaid member 7, so that no movement of the lreciprocating' carriage cwill take place during' this movement of the actuator (j. The carriage cis thus held in the position shown in Fig. 5, in which the punch membersand n are in position to punch a hole in the paper, and during' thistime the punching member r/ is acted upon by a cam ,r/g, formed on theactuating' member g, the said cam bearing' directly upon the top Of thepunch (t, s0

as to force the same downward and punch the paper. The actuator r/ isthen turned in the opposite direction, and the punch (l, being' releasedby the cam (y2, rises through the action of the spring' fr, the cam-rolld' reaching' the portion c" of the cam-groove in the member a at aboutthe time when the punch has reached its normal position. The action ofthe cam-groove at this period in the operation is to swing' the lever Zupon its pivot (Z2 and move the carriage c to the left, thus bringii'ig'the setting' members L and b2 into the position previously occupied bythe liunching' members, so that they are in alinement with the hole madeby the punch, the papers nothaving'been moved in the meanwhile. Acontinued movement of'the actuating' member y] to the rig'ht asindicated in Fig. 6 will produce no further movement of the carriage c,since the portion e of the cam-groove e is also curved on an arc struckfrom the center of oscillation of the supporting'memberf Such movement,however,is communicated to the upper setting' member throug'h the agencyof a link 7;, which is pivotally connected at 7)" to the upper end ofthe setting' member the said link b being' operated upon in turn by apin g3, which enters a slot f in the link eng'ag'ing' the bottom of saidslot and depressing' the link and setting' device 7) as the actuating`member f/ is pushed over to the position shown in Fig'. 6. The lowersetting' device L2 having' been previously provided with a fastening'device, such as an eyelet, thus presents the eyelet to the opening' andthe eyelet is clenched, as shown in Fig. 6. Upon restoring' the handle 0to its intermediate position the setting' devices are separated fromeach other and the papers, properly fastened, may be removed.

In order to supply the lower setting` device t2 with the fastening`devices, the machine is shown as provided with a feed-chute L, leadingfrom a suitable hopper 7L, which is adapted to contain a mass ofeyelets, which travel down the chute, the lowermost eyelet being' heldin the end of the chute by means of the ordinary spring-gate oryielding' member, which prevents the eyelet from falling' from the chutethrough its own gravity, but permits the eyelet to be pulled from thechute if Y extraneousl f eneao'ed. To engage and feed the u b Dlowermost eyelet, the lower setting' device 7X5 is shown as providedwith a depressible ling'er L, which is normally pressed upward. by meansof a spring' 7)?, but arranged to be eng'ag'ed by a suitable retaining'device after it has been depressed during' the operation of setting' theeyelet.

As herein shown, the linger 7) is provided at its lower end with atapered projection lf, above which is a shoulder 7;", the said taperedprojection being' arranged to engage a slot which is formed between twoseparable members 7u, secured to the under side of the frame TOO VlIO

A by means of screws 7a2 and normally held together by means of springssaid members, however, having slots 1* (dotted lines, Fig. 4) wherebythey may-be moved laterally to separate them. T he said members are eutto form a slot between them substantially equal in width to the diameterof the finger 71", but smalier than the diameter of the shoulder 7;", sothat when the said linger is forced downward by the upper set, as shownin Figs. 3, 4, and 6, the tapered member bs will push through,separating the members 1, which will spring together after the shoulder7) has passed below the said members r, which members then constitute aretaining device to prevent the upward movement of the fing'er. The slotfor the said linger 7) extends along the members in the direction ofmovement of the carriage c, and at the point where the said lingerreaches the feed-chute /t the said slot is widened so as to afford spacesuihcient to permit the passage of the shoulder 69, thus permitting theupward movement of the finger b in response to the action of the spring,717. The finger L then being below the end of the chute z, it isobvious that the finger will enter an eyelet in said -chute and engagethe same, so that'it will carry away the said eyelet during the nextreciprocating movement of the carriage c, properly presenting the sameto the upper setting device 7), which is then in the position tocomplete the setting operation.

During the fastening operation the paper is supported upon a table m,which is shown as a frame having' a large middle opening for theoperation of the fastening devices, the said table being supported uponthe frame A by means of studs m2 at opposite sides of the machine. Thepaper is held in position by means of a retaining device, which is shownas mounted on a rock-shaft n, having bearings n2 upon the table m, thesaid rock-shaft being provided with a spiral spring 11,3, the tendencyof which iste hold the same in the position shown in Fig. l. The paperis retained in position by means of spring-fingers w", connected withthe said rock-shaft 71y and arranged to be moved toward the surface ofthe table m, so as to hold the paper thereon. rlhese lingers normallystand away from the table, as shown in Fig. l, and the carriage c isalso provided with a guide member c4, which, in conjunction with thetable mi, tends to hold the loose sheets of paper together until thesaid sheets are engaged by the fingers 01.*. The said fingers arearranged to be pressed downward upon the surface of the papers duringthe lirst movement of the actuating-handle g, which produces theoperation of the punch a, this being accomplished by means of anactuating member o, shown as pivotally supported upon the side of thecarriage c and arranged to be acted upon by a cam-surface e, formed onthe member e2, and in turn to act upon a radially-projecting member a5,secured to the rock-shaft a. This cam 0 normally stands in the positionshown in Fig. l, being limited in its movement by a stop 02,- but in thefirst movement of the actuating member g to the left the said cam isengaged by a projection e7, formed on the cam-surface e, which turns ittoward the right, causing it to act upon the arm a5 and force thefingers n* down toward the paper supported upon the table m. The membero will remain in this position during the subsequent operations ofpunching the paper and shifting the carriage, but will be restored toits normal position during the setting operation, in which thecam-surface e strikes the member 0 and moves it back into its normalposition.
